Biography
In response to Zhuge Liang's Northern Expeditions, he served in the vanguard under Cao Zhen. Suspicious of Jiang Wei's desire to join Wei, he rode out instead of Cao Zhen and allowed Jiang Wei into the camp. He remained cautious and moved carefully, but he still fell for Jiang Wei's clever plot and took his own life as the enemy closed in.
